CAR-COUPLiNG.

SPECIFICATION forming part of Letters Patent No. 414,648, dated November 5, 1889.

Application tiled November 30, 1888. Serial No. 292,840. (No model.)

To all whom, t may concern,.-

Be it known that I, ELIJAH LEMAs'rERs, a citizen of the United States, residing at Pecria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in OarCouplings; and I do hereby declare that the following' is a full, clear, and exact description of the invention, which will en able others skilled in the art to which it appertains to make and use the same.

My invention relates to car-couplings; and it consists in theimproved construction hereinafter described, whereby an efficient and positively-operating device is provided, and one in which the connections may be readily severed to effect the detachment of the adjacent couplings.

In the accompanying drawings, forming part of this specification, Figure l is a side plan view of a car-coupling embodying my improvements, and Fig. 2 is a vertical longitudinal section oi1 said improved coupling. Fig. 3 is an end view of my invention. Fig. -i is the link-bar and lug.

The dra-whead A is provided with the usual mouth at its front, through which extends the link-bar D, which is provided at its extremity with the iiat horizontal barbhead. The said link-bar D is provided in its rear part with a horizontallyelongated slot, through which passes a horizontal pin p, which is carried in recesses 0r depressions in the lug c., which serve, in connection with the bolt -m and the spring z, to permanently secure the said bar D within the head, and also to hold it in its Within the draw-head and at either side of the link D is a horizontal lever B, which is centrally pivoted, as at Z, and is provided at each end with an inwardlyextending hook-extension t t, being of equal length and extending close to the sides of the link D and carrying at their rearextension the rollers f f. An operating-lever d, provided for each lever B, is pivoted, as at h, and at its forward end carries the pulley t' fi, through which passes the chain 7c, which connects with a pulley y, which is carried by the lug h, and said chain being finally connected with the arms of the lever n.

o o are springs useful to hold or restore the levers B to their proper position.

In practice it wllbe understood that the link-bar of the other coupling device corresponding to the bar D -is located in a higher or lower plane than said bar D, as the occasion may be, and as itapproaches the bar D its barb-head strikes the surface of the barbhead and rides over the same, contacting with the jaw-extensions t t, which yield to allow said head .to pass into the jaw-head, and which becomes locked therein,by reason of its barbed form, after it has passed the jaws. It will be understood that this operation occurs in both couplings. To disconnect the couplings it will only be necessary to draw the spring-lever rearwardly, so as to effect the separation of the levers B B, so that they, owing to their intermediate connections and pivots, will eect the outward movement of the jaws t t to permit the barb-head b to be readily withdrawn.

From the foregoing it will be obvious that the device is simple and positive in its operation and avoids many objections incident to ordinary forms of car-couplin gs.

I claim- 1. The combination, in a car-coupling, of the link-bar D with the levers B, with the pivoted lever d, with the pulleys c' c' and the pulleys y y, with the chains la k, and with the lever n, substantially as set fort-h.

2. The combination, in a car-coupling, of the link-bar D, carried in the lng a and held in position by means of the bolt fm and the spring e', with the jaws B, with the springs o o, with the pivoted levers d d, and suitable means for operating said combination.

3. In combination, the barb-headed linkbar carried in the lug a with the jaws B, carrying the rollers f, which work on the inner surface of the pivoted lever d, which carries the pulley c', and the lug b, carrying the pulley y, in which runs the chain k and connects with the lever n, substantially as described.

4. In combination, the barb-headed linkbar D with the jaws B B, carrying the rollers ff, with the pivoted levers d d, with the pulleys 'L' z', with the lugs b b, with the pulleys 'y y, with the chains k, and with the lever n, substantially as described.

5. In combination,the link-bar D, provided with the barb-head, pivoted jaws B B, located in the same vertical plane carrying the rollers f f, the pivoted levers d d, and appliances IOO for operating said jaws, substantially as set In testimony whereof Iafx my signature in 1o forth. presence of two witnesses.
